Structure-reactivity correlations for complex formation reactions between square-planar metal centers and thioethers

Kinetics for complex formation between Pd(H2O)(4)(2+) and thioethers of largely varying electronic and steric properties, viz. MeSCH(2)COOH, (n-Pr)(2)S, EtSCH(2)CH(2)OH, S(CH2CH2CH2OH)(2), S(CH2CH2OH)(2), EtSCH(2)COOH, S(CH2COOH)(2), S(CH2CH2COOH)(2), (i-Pr)(2)S, (s-Bu)(2)S, (t-Bu)(2)S, and protonated thiomorpholine, S(C2H4)(2)NH2+, has been studied by use of stopped-flow spectrophotometry in an acidic aqueous medium. Second-order rate constants k(1)(298) are 1.61 x 10(4), 8.0 x 10(4), 3.79 x 10(4), 3.69 x 10(4), 2.21 x 10(4), 1.84 x 10(4), 1.91 x 10(3), 1.34 x 10(4), 1.52 x 10(4), 7.75 x 10(3), 900, and 5.2 x 10(3) M(-1) s(-1), respectively. The reactivity toward Pd(H2O)(4)(2+) of all thioethers studied so far can be described as a function of their sigma-donor properties as expressed by the sum of the Taft constants, Sigma sigma*, and their steric requirements as defined by cone angles, theta, by use of the equation: log k(1) = (9.9 +/- 0.3) – (0.67 +/- 0.05)Sigma sigma* – (0.059 +/- 0.003)theta. Similarly, second-order rate constants k(298) reported previously for reactions between thioethers and Pd(dien)H2O2+ and Pt(dienBr+ are described by log k(298) = (10.5 +/- 0.6) – 0.67 Sigma sigma* – (0.081 +/- 0.006)theta and log k(298) = (4.6 +/- 0.6) – 0.72 Sigma sigma* – (0.080 +/- 0.006)theta, respectively. Hence, the reactivity trends of thioethers toward square-planar complexes can be given a general interpretation in terms of intrinsic, electronic, and steric parameters, by use of log k = gamma + alpha Sigma sigma* + beta theta. Large variations in both electronic and steric properties of the entering ligands indicate that there is no ”duality behavior” in the reactions of thioethers with square-planar metal centers, as claimed in previous literature. No steric threshold is observed for these sterically unhindered systems. There is a rough compensation effect between Delta H-1 double dagger and Delta S-1 double dagger, i.e. a smaller Delta H-1 double dagger is usually accompanied by a larger negative Delta S-1 double dagger, indicating that all thioethers react via the same mechanism. It appears that the much lower reactivity observed for the highly branched (t-Bu)(2)S is primarily caused by a high activation enthalpy. Volumes of activation have been determined for a series of thioethers with a constant cone angle, viz. EtSCH(2)COOH, S(CH2COOH)(2), and S(CH2CH2COOH)(2) through high-pressure stopped-flow measurements. Values of Delta V-1 double dagger are -7.9 +/- 0.5, -8.1 +/- 0.4, and -7.6 +/- 0.3 cm(3) mol(-1), respectively. These values together with that for Et(2)S (-8.7 +/- 0.1 cm(3) mol(-1)) determined previously shows that variation of electronic properties, steric factors being kept constant, change the reactivity markedly, but have no observable influence on the activation volumes. Stability constants beta(1) for five palladium thioether complexes derived as the ratio between rate constants for forward and reverse reactions vary between (1.2 +/- 0.3) x 10(4) and (3.2 +/- 0. 7) x 10(4) M(-1).

Synthesis and in vitro anti-Helicobacter pylori activity of N-[5-(5-nitro-2-heteroaryl)-1,3,4-thiadiazol-2-yl]thiomorpholines and related compounds

Synthesis and in vitro anti-Helicobacter pylori activity of N-[5-(5-nitro-2-heteroaryl)-1,3,4-thiadiazol-2-yl]thiomorpholines 5-7(a-c) and some related compounds 8a-c and 9a-c were described. The anti-H. pylori activity of target compounds along with commercially available antibiotics such as metronidazole and amoxicillin was evaluated by comparing the inhibition zone diameters determined by the paper disc diffusion bioassay. From our bioassay results against 20 clinical isolates, it is evident that most compounds still had strong activity at 4 and 2 mu g/disc (average of inhibition zone > 20 mm) while metronidazole had little activity at these doses. Nitrofuran analog 7b containing thiomorpholine S,S-dioxide moiety was the most potent compound tested. (c) 2007 Elsevier Masson SAS. All rights reserved.

Enhancers were applied at 0.4 M in propylene glycol (PG) (or as a suspension) to mouse skin. Hydrocortisone (0.03 M in PG) was applied 1 h following enhancer treatment. Controls (no pretreatment) yielded 24 h diffusion cell receptor concentrations (Q(24)) of 9.93 +/- 3.15 mu M and model drug skin retention of 26.1 +/- 5.6 mu g g(-1). Compound 7 yielded a high Q(24) of 208.18 +/- 39.52 mu M. The highest skin retention was observed with 6 of 566.7 +/- 39.7 mu g g(-1). Azone gave values of 218.96 +/- 47.84 mu M for Q(24) and 294.9 +/- 66.7 mu g g(-1) for skin retention.

The effect of heterocyclic S,S ‘-ligands on the electrochemical properties of some cobalt(III) complexes in acid

Eight mixed-ligand cobalt(III) complexes with the macrocyclic amine 1,4,8,11 -tetraazacyclotetradecane (cyclam) and a heterocyclic dithiocarbamate (Rdtc(-)) i.e., morpholine- (Morphdtc), thiomorpholine- (Timdtc), piperazine- (Pzdtc), N-methylpiperazine- (Mepzdtc), piperidine- (Pipdtc), 2-, 3- or 4-methylpiperidine- (2-, 3- and 4-Mepipdtc) carbodithionato-S,S ions, of the general formula [Co(cyclam)Rdtc](ClO4)(2), were investigated in deoxygenated 0.1 M HClO4 solutions. Cyclic voltammetry data at a glassy carbon (GC) electrode demonstrate a redox reaction of cobalt(III) from the complexes at potentials strongly influenced by the presence of different heterocyclic Rdtc(-) ligands. In this respect, the complexes were separated into two groups: the first, with a heteroatom O, S or N in the heterocyclic ring, and the second, with a methyl group on the piperidine ring of the Rdtc(-) ligand. Anodic polarization of an Fe electrode in the presence of the complexes shows their influence not only on the dissolution of iron but also on the hydrogen evolution reactions and on this basis complexes the complexes could be divided into the same two groups. It was found that the weaker the inhibiting effect of the free heterocyclic amines is, the significantly higher is the efficiency of the corresponding complexes.

Development of a Safe and High-Throughput Continuous Manufacturing Approach to 4-(2-Hydroxyethyl)thionnorpholine 1,1-Dioxide

Continuous processing enabled the highly energetic double conjugate addition of ethanolamine to divinylsulfone to prepare 2 kg of 4-(2-hydroxyethyl)thiomorpholine 1,1-dioxide, as an intermediate in the synthesis of HIV Maturation Inhibitor BMS-955176. In situ IR was employed to monitor the steady state of the transformation for increased robustness via appearance of the thiomorpholine dioxide moiety and disappearance of the divinylsulfone. Surprisingly, a series of oligomers formed as intermediates, which converted to product with extended aging or heating, consistent with computational predictions. By running this process in flow, the highly exothermic reaction could be safely executed in an equal volume of water as the only solvent, despite an adiabatic temperature rise of 142 degrees C, leading to a streamlined and efficient process.

Fusion and Desulfurization Reactions of Thiomorpholinochlorins

An unusually nonplanar, ruffled structure that had been suspected for the previously reported [2,3-bismethylenethiomorpholinochlorinato] nickel (II) complex was confirmed by determination of its crystal structure. Treatment of this thiomorpholinochlorin with acid converts the exocyclic double bonds to direct links to the ortho-positions of both adjacent meso-phenyl groups. The crystal structure of this product indicated that the introduction of these linkages did not change the overall conformation of the macrocycle. The reactivity of the bis-linked thiomorpholine moiety with respect to Raney-nickel-induced (hydro)desulfurization reactions was probed, forming a bis-phenyl-linked 2,3-dimethylchlorin, also characterized by X-ray diffraction, and a bis-indeneannulated porphyrin. We also report on the synthesis of the oxygen analogue to the bis-linked thiomorpholine by reaction of a secochlorin bisketone nickel complex with Woollins’ reagent. We thus introduce novel methodologies toward the synthesis of porphyrinoids carrying beta-to-ortho-phenyl fusions and expand on the scope and limits of the chemistry and interconversion of pyrrole-modified porphyrins.
